Silicone Rubber Heating Tape

The silicone rubber electric heating tape uses a glass fiber woven framework and a resistive heating element, with an overall external flexible silicone rubber coating. The tape body can be attached to or wrapped around pipes, valves, containers, laboratory equipment, and irregular surfaces for direct heating, frost protection, and insulation; when in use, it requires a matching temperature sensor and controller to limit the temperature of both the heated object and the tape.

Low-Temperature Self-Regulating Heat Tracing Cable

The low-temperature self-regulating heat tracing cable uses two parallel bus wires and a PTC semiconductor polymer heating core tape. The core tape automatically adjusts output according to local pipe temperature changes: power increases when the temperature drops and decreases when the temperature rises. It is suitable for freeze protection, anti-freezing, and maintaining process temperatures up to 65°C for pipelines, valves, tanks, and equipment in water supply and drainage, fire protection, petrochemical, and other industries.

  • PTC core tape adjusts heating output segment by segment, adapting to different heat dissipation at various pipe positions
  • Parallel busbar structure, can be cut to installation size within the specified maximum loop length
  • self-regulating feature reduces the risk of continuous overheating at overlapping installation positions
